What, the headline doesn’t tell you all you need to know about Johnny Knoxville’s latest project?

Fine. Jackass Presents: Bad Grandpa stars Knoxville as Irving Zisman, a dirty old man who loves three things above all else: “poontang,” making a spectacle of himself, and his young grandson/wingman (Jackson Nicholl). Previous trailers for this hidden camera comedy featured Irving ruining a wedding and crashing a kiddie beauty pageant; this latest red-band clip features a lot more swearing, as well as a delightful scene of Knoxville getting his (prosthetic) Little Grandpa stuck in a vending machine.
